Abstract
A composition is provided that includes 0.5 to 15 total weight percent of a surfactant. The surfactant is a non-ionic surfactant, an anionic surfactant, or a combination thereof. The composition also includes 0.01 to 35 total weight percent of solvent including a microemulsion, a carboxylic acid ester based ketal ester solvent, or a combination thereof. 0.1 to 10 total weight percent of at least one emollient, and 60 to 99.3 total weight percent of water also being present. The resultant composition has total volatile organic content (VOC) composition of less than 2 total weight percent and as a result, the composition is more environmental benign and less irritating to skin than conventional waterless hand cleaners. The composition is well suited for being impregnated into a substrate of a towel presenting two opposed surfaces, the substrate having pores for absorbing and retaining the composition.
Description
LOW VOC CONTENT WATERLESS CLEANER AND ARTICLE IMPREGNATED
THEREWITH
RELATED APPLICATIONS
[0001] This Canadian application claims priority benefit of U.S. Provisional application Serial Number 61/585,763 filed on 12 January 2012 and United States Serial Number 13/709,116 filed December 10, 2012; the contents of both may be referred to for further details.
FIELD OF THE INVENTION
[00021 The present invention in general relates to a cleaning composition for removal of lipophilic substances such as paints, resins, oils, and organic soils from skin and hard surfaces, and in particular to waterless cleaning composition for doing so with low VOC
content.
BACKGROUND OF THE INVENTION
[0003] Waterless hand cleaners routinely have a gelatinous consistency. These cleaners often have both hydrophilic and hydrophobic components which are blended together to affect removal of a wide variety of soils from the skin surface. While the gelatinous hand cleaner is effective in removal of material from the skin surface, subsequent water washing is invariably required to remove the residual debris filled gel. Additionally, a gel independent of an abrasive is often slow in removing substance from the skin surface. Conventional waterless cleaning compositions often contain as much as 45% by weight of organic solvents and high loadings of emulsifiers in order to solubilize grease and soil. These compositions require high concentrations of organic solvents and emulsifiers to remove hydrophobic materials through dual actions of emulsification and solvation.
[0004] Low viscosity, liquid waterless hand cleaners have proven popular and effective when used in conjunction with an abrasive article that retains the liquid in contact with the skin surface and provides mechanical action to disrupt soil or grease films on the skin surface. Representative of such products are those detailed in U.S. Patent 5,683,971 in which an abrasive coated towel retains the cleaning composition.
[0005] Regardless of the viscosity, these conventional cleaning compositions have fallen out of favor owing to the high loading of organic solvents and emulsifiers that end up in wastewater, as well as the skin irritation associated with the use of such products. Volatile organic compound content (VOC) in consumer products is now tightly regulated and the acceptable limits of VOCs in such products are constantly being lowered. The high concentration of organic solvents and emulsifiers present in these conventional cleaner also makes subsequent removal of the cleaner difficult, often resulting in a residual film that retains soil and/or grease while the film tends to dry and irritate the underlying dermis. Owing to the environmental impact, cost, and skin irritation caused by contact with cleaner residue, there is a desire to reduce the usage of such solvents without compromising the cleaning ability of such waterless hand cleaners.
[0006] Thus, there exists a need for a cleaning composition that is amenable to impregnation into an article that has reduced ecotoxicity and improved skin compatibility while remaining effective against soils and greases.
SUMMARY OF THE INVENTION
[0007] A composition is provided that includes 0.5 to 15 total weight percent of a surfactant. The surfactant is a non-ionic surfactant, an anionic surfactant, or a combination thereof. The composition also includes 0.01 to 35 total weight percent of solvent including a microemulsion, a carboxylic acid ester based ketal ester solvent, or a combination thereof.
0.1 to 10 total weight percent of at least one emollient and 60 to 99.3 total weight percent of water is also present. The resultant composition has total volatile organic compound content (VOC) is less than 2 total weight percent and is more environmental benign and less irritating to skin than conventional waterless hand cleaners.
[0007a] The aforementioned composition may also include at least one of a pH
adjusting material, an antioxidant, a fragrance, a dye, and a foaming agent.
[0008] The composition is well suited for being impregnated into a medium of a towel presenting two opposed surfaces, the substrate having pores for absorbing and retaining the composition. An abrasive ingredient adhered to at least one of the two opposed surfaces at least one said surface to facilitate mechanical removal of substances from the skin surface of a user.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0009] The present invention has utility as a free flowing, liquid cleaning composition especially well suited for removal of paint, resin, oils, and lipophilic soils from the skin surface with a low VOC content or no VOC content. The inventive cleaning composition is particularly well suited as a hand cleaner for removing such substances and soils from a user's skin in combination with a towel, such as that detailed in U.S. Patent 4,833,003. The inventive composition is optionally pre-wet and impregnated into the article. Such wet articles are amenable to packaging in a container as a pre-perforated roll or stack of such articles that can be dispensed, used and discarded to affect cleaning without resort to a secondary water washing or cleaner removal.

Owing to the environmental impact, cost, and skin irritation caused by contact with cleaner residue, there is a desire to reduce the usage of such solvents without compromising the cleaning ability of such waterless hand cleaners.
[0006] Thus, there exists a need for a cleaning composition that is amenable to impregnation into an article that has reduced ecotoxicity and improved skin compatibility while remaining effective against soils and greases.
SUMMARY OF THE INVENTION
[0007] A composition is provided that includes 0.5 to 15 total weight percent of a surfactant. The surfactant is a non-ionic surfactant, an anionic surfactant, or a combination thereof. The composition also includes 0.01 to 35 total weight percent of solvent including a microemulsion, a carboxylic acid ester based ketal ester solvent, or a combination thereof.
0.1 to 10 total weight percent of at least one emollient and 60 to 99.3 total weight percent of water is also present. The resultant composition has total volatile organic compound content (VOC) is less than 2 total weight percent and is more environmental benign and less irritating to skin than conventional waterless hand cleaners.
[0007a] The aforementioned composition may also include at least one of a pH
adjusting material, an antioxidant, a fragrance, a dye, and a foaming agent.
[0008] The composition is well suited for being impregnated into a medium of a towel presenting two opposed surfaces, the substrate having pores for absorbing and retaining the composition. An abrasive ingredient adhered to at least one of the two opposed surfaces at least one said surface to facilitate mechanical removal of substances from the skin surface of a user.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0009] The present invention has utility as a free flowing, liquid cleaning composition especially well suited for removal of paint, resin, oils, and lipophilic soils from the skin surface with a low VOC content or no VOC content. The inventive cleaning composition is particularly well suited as a hand cleaner for removing such substances and soils from a user's skin in combination with a towel, such as that detailed in U.S. Patent 4,833,003. The inventive composition is optionally pre-wet and impregnated into the article. Such wet articles are amenable to packaging in a container as a pre-perforated roll or stack of such articles that can be dispensed, used and discarded to affect cleaning without resort to a secondary water washing or cleaner removal. By

3 reducing the VOC content of an inventive composition relative to the prior art, the environmental impact of the product is reduced along with the residual skin irritation.
[0010] As used herein, a VOC is defined as a compound listed on the United States Environmental Protection Agency Volatile Organic Compounds Master List.
[0011] An inventive composition is able to replace in part, or total regulatory controlled VOCs and still remain effective at removing lipophilic soils and greases through reliance on with from 0.1 to 35 total weight percent of a non-VOC microemulsion or 0.01 to 35 total weight percent of a non-VOC ketal ester, of a combination thereof with a combined loading of 0.1 to 35 total weight percent to replace in whole or part conventional waterless hand cleaner VOCs such as mineral spirits, limonene, and dibasic esters. The inventive composition also contains water present from 60 to 99.7 total weight percent; a surfactant of non-ionic or anionic type; along with optional additives forms a superior liquid cleaning composition; alone or when used in combination with a cleaning article. It is appreciated that all or part of the inventive solvent is replaced with vegetable oils, terpenes, or a combination thereof with the proviso that the VOC
content remains below 5 total weight percent and preferably below 1 total weight percent.
[0012] The present invention reduces VOC content, skin irritation, and has storage stability while maintaining conventional cleaning properties with respect to paints, resins, and other lipophilic soils. Through selection of specific additives, antibacterial treatment is achieved and skin quality is also improved.

[0020] Preferably, the inventive composition is impregnated or even saturated into a towel preferably when the towel is hydrophob. It is appreciated that frictional forces applied between a towel surface even if lacking an abrasive and a target surface to be cleaned is sufficient to promote soil removal or a soil film therefrom. More preferably, the towel has an abrasive adhered to at least one of the opposing surfaces thereof A plurality of abrasive towels are readily provided in a continuous, perforated, rolled cylinder of towels or as a stack of such towels. The line of perforation presents a line of weakness by which the towels can be easily separated.

The inventive composition is then added to the container, preferably by pouring the same over the cylinder of towels, thereby moistening the towels with the inventive cleaning composition within the container. The capillary action associated with the void volume of the towel as discussed above causes the inventive cleaning formulation to be evenly distributed throughout the cylinder of towels.
[0021] An example of a suitable container for holding the towels is an essentially airtight lid on a cylindrical or hexahedral rectilinear container defining an interior volume, the lid can be selectively sealed, the lid having a hinged cap. The opening of the cap allows for the passage of towels from the interior of the sealed container via the opening, so individual towels can be removed from the interior container by pulling the towel and tearing the same off of the towel roll at the perforated line located between each individual towel. The opening is appropriately sized to allow for the removal of excess liquid from each individual towel as it is removed from the container. Alternatively towels are accordion folded and stacked in a hexahedral container and the top towel drawn through the lid.
[0022] In use, an individual towel is removed from the container as described above. When properly prepared, the towel contains an amount of cleanser sufficient to thoroughly cleanse the skin of the user. As the towel is rubbed on the skin, it releases the liquid cleaner and allows it to have extended contact time with the skin, and also provides for continuous cleaning without the need to apply additional cleaner. The abrasive character of the towel facilitates removal of embedded soils without leaving any abrasive residue on the skin. Residue would otherwise necessitate rinsing the skin with water after the cleansing process to thoroughly remove such abrasive residue. However, it is appreciated that an abrasive free and an inventive composition
It is appreciated that the overall loadings of emulsifiers of the present invention and combinations thereof are somewhat variable based on specific identities;
however, factors relevant in selecting the quantity of emulsifiers include quantity of microemulsion present, composition viscosity, ketal ester amount and properties.

[0019] Optional additives to a base inventive composition that are well suited for the formation of a liquid hand cleaning composition include: fragrance compounds that are optionally present from 0.001 to 3 total percent; polyvalent metal ion salts such as magnesium oxide, magnesium sulfate, magnesium hydroxide, magnesium chloride, magnesium carboxylates, magnesium halides, magnesium nitrates, as well as aluminum, iron, calcium, and other polyvalent metal ions forming salts with these anions, the polyvalent metal ion salts are optionally present from 0 to 2 total weight percent and are well suited for improving lipophilic soil lift in water containing higher salt loadings; an antimicrobial to improve storage stability illustratively includes quaterniums, triclosan, PCMX, and other conventional antibacterials, an antimicrobial is optionally present from 0 to 2 total weight percent and preferably. between 0.005 and 1 total weight percent; a foaming agent is optionally present from 0 to 2 total weight percent and preferably, between 0.2 and 0.6 total weight percent; dibasic esters are typically present between 0 and less than 0.4 total weight percent and preferably, present at less than 0.2 total weight percent; a colorant is optionally present in an amount of from 0 to 1 total weight percent and preferably, from 0 to 0.3 total weight percent; and a pH modifying source of a mineral acid, organic acid, or hydroxide source such as sodium hydroxide or potassium hydroxide is optionally present in a quantity appropriate to adjust overall inventive composition pH to a desired value while preserving pH storage stability and phase stability thereof An inventive composition typically has pH values range from 6 to 9 fully formulated.
[0020] Preferably, the inventive composition is impregnated or even saturated into a towel preferably when the towel is hydrophob. It is appreciated that frictional forces applied between a towel surface even if lacking an abrasive and a target surface to be cleaned is sufficient to promote soil removal or a soil film therefrom.

The opening of the cap allows for the passage of towels from the interior of the sealed container via the opening, so individual towels can be removed from the interior container by pulling the towel and tearing the same off of the towel roll at the perforated line located between each individual towel. The opening is appropriately sized to allow for the removal of excess liquid from each individual towel as it is removed from the container.

When properly prepared, the towel contains an amount of cleanser sufficient to thoroughly cleanse the skin of the user. As the towel is rubbed on the skin, it releases the liquid cleaner and allows it to have extended contact time with the skin, and also provides for continuous cleaning without the need to apply additional cleaner. The abrasive character of the towel facilitates removal of embedded soils without leaving any abrasive residue on the skin. Residue would otherwise necessitate rinsing the skin with water after the cleansing process to thoroughly remove such abrasive residue. However, it is appreciated that an abrasive free and an inventive composition
8
9 suspended are operative to clean a target surface. Thus, a waterless hand cleaner article is provided without the negative features associated with the conventional waterless hand cleaners of the prior art.
[0023] The inventive composition also assures efficient use of the cleaner, as the proper amount of cleaner is provided for each individual use. Other low viscosity liquid cleaners tend to be wasted as the low viscosity associated with such cleaners often causes them to run off of the skin. Gelatinous cleaners are also difficult to use efficiently, as the user often utilizes too little, thereby necessitating a repeated application; or too much, requiring a cloth or towel to remove the wasted excess.
[0024] Furthermore, the towel of the present invention acts not only as a medium for the cleaning formulation and as a vehicle for the abrasive ingredient, but it also serves to dry the skin after the cleanser has been used and has partially evaporated from the towel.
[0025] The present invention is further detailed with respect to the following nonlimiting examples. Unless otherwise specified, the percentages detailed herein are total weight percent of the inventive formulation.
Example 1 [0026] To 500 milliliters of municipal water is added sequentially 27 grams of C12-C15 non-ionic surfactant with 7 moles ethylene oxide (EO), 22 grams of a microemulsion is then added, the microemulsion being composed of 20 emulsion percent sodium di(hexyl)sulfosuccinate, 40 percent dibasic esters, and 10 microemulsion weight percent of polyethylene glycol (MW 200).
With addition of the microemulsion, additional components are added including 15 grams of ISOPAR M (hydrocarbon solvent); 5 grams of butyl hydroxytoluene (BHT); 3 grams of propylene glycol; 3 grams isopropyl myristate; 2.5 grams fragrance; 4 grams of vegetable oil;
and 1 gram each of lanolin, aloe vera, vitamin E oil, and jojoba oil. The volume is brought to approximately 1 liter with the addition of more municipal water and the mixture is stirred at 20 Celsius until homogeneous. The resultant composition is saturated into a towel having an abrasive adhered to a surface and constitutes an effective liquid hand cleaner able to solubilize or otherwise lift more than 0.1 grams petroleum jelly per gram of inventive hand cleaner composition from hands with 2 minutes of interworking on user hands.
Example 2 [0027] The cleaning composition of Example 1 is reformulated with 49 grams of levulinic acid based ketal in lieu of the microemulsion detailed above in Example 1 with the quantity of water being adjusted to compensate for differential in other components. A cleaning composition and abrasive article with similar properties to that of Example I is produced.
Example 3 [0028] The cleaning composition of Example 1 is reformulated with 25 grams of levulinic acid based ketal and 12 grams of the microemulsion in lieu of the 22 grams of microemulsion detailed above in Example 1 with the quantity of water being adjusted to compensate for differential in other components. A cleaning composition and abrasive article with similar properties to that of Example 1 is produced.
Comparative Example [0029] In order to assess the relative cleaning ability of inventive compositions, the comparative removal of the Example 3 composition is contrasted with that of a control composition. The control composition is formulated per U.S. Patent 5,683,971 preferred composition that is saturated into an abrasive towel substrate per U.S. Patent 4,833,003. The composition of Example 3 and the Comparative Example afford like cleaning properties.
[0030] Patent documents and publications mentioned in the specification are indicative of the levels of those skilled in the art to which the invention pertains. These documents and publications may all be referred to for further details.
[0031] The foregoing description is illustrative of particular embodiments of the invention, but is not meant to be a limitation upon the practice thereof. The following claims, including all equivalents thereof, are intended to define the scope of the invention.
[0023] The inventive composition also assures efficient use of the cleaner, as the proper amount of cleaner is provided for each individual use. Other low viscosity liquid cleaners tend to be wasted as the low viscosity associated with such cleaners often causes them to run off of the skin. Gelatinous cleaners are also difficult to use efficiently, as the user often utilizes too little, thereby necessitating a repeated application; or too much, requiring a cloth or towel to remove the wasted excess.
[0024] Furthermore, the towel of the present invention acts not only as a medium for the cleaning formulation and as a vehicle for the abrasive ingredient, but it also serves to dry the skin after the cleanser has been used and has partially evaporated from the towel.
[0025] The present invention is further detailed with respect to the following nonlimiting examples. Unless otherwise specified, the percentages detailed herein are total weight percent of the inventive formulation.
Example 1 [0026] To 500 milliliters of municipal water is added sequentially 27 grams of C12-C15 non-ionic surfactant with 7 moles ethylene oxide (EO), 22 grams of a microemulsion is then added, the microemulsion being composed of 20 emulsion percent sodium di(hexyl)sulfosuccinate, 40 percent dibasic esters, and 10 microemulsion weight percent of polyethylene glycol (MW 200).
With addition of the microemulsion, additional components are added including 15 grams of ISOPAR M (hydrocarbon solvent); 5 grams of butyl hydroxytoluene (BHT); 3 grams of propylene glycol; 3 grams isopropyl myristate; 2.5 grams fragrance; 4 grams of vegetable oil;
and 1 gram each of lanolin, aloe vera, vitamin E oil, and jojoba oil. The volume is brought to approximately 1 liter with the addition of more municipal water and the mixture is stirred at 20 Celsius until homogeneous. The resultant composition is saturated into a towel having an abrasive adhered to a surface and constitutes an effective liquid hand cleaner able to solubilize or otherwise lift more than 0.1 grams petroleum jelly per gram of inventive hand cleaner composition from hands with 2 minutes of interworking on user hands.
Example 2 [0027] The cleaning composition of Example 1 is reformulated with 49 grams of levulinic acid based ketal in lieu of the microemulsion detailed above in Example 1 with the quantity of water being adjusted to compensate for differential in other components. A cleaning composition and abrasive article with similar properties to that of Example I is produced.
Example 3 [0028] The cleaning composition of Example 1 is reformulated with 25 grams of levulinic acid based ketal and 12 grams of the microemulsion in lieu of the 22 grams of microemulsion detailed above in Example 1 with the quantity of water being adjusted to compensate for differential in other components. A cleaning composition and abrasive article with similar properties to that of Example 1 is produced.
Comparative Example [0029] In order to assess the relative cleaning ability of inventive compositions, the comparative removal of the Example 3 composition is contrasted with that of a control composition. The control composition is formulated per U.S. Patent 5,683,971 preferred composition that is saturated into an abrasive towel substrate per U.S. Patent 4,833,003. The composition of Example 3 and the Comparative Example afford like cleaning properties.
[0030] Patent documents and publications mentioned in the specification are indicative of the levels of those skilled in the art to which the invention pertains. These documents and publications may all be referred to for further details.
[0031] The foregoing description is illustrative of particular embodiments of the invention, but is not meant to be a limitation upon the practice thereof. The following claims, including all equivalents thereof, are intended to define the scope of the invention.
